相控阵探地雷达数据傅氏有限差分偏移研究

Study on Fourier Finite-difference Depth Migration Method in Phased-array Ground-penetrating Radar Data

摘要:

偏移归位是探地雷达资料处理中的一种重要方法。本文利用傅里叶有限差分法对相控阵探地雷达样机采集的实测数据进行偏移归位。异常点绕射波形得到有效的归位,异常体空间位置与实际测量的结果基本一致并且处理速度快,不仅表明了该方法的有效性,证明相控阵探地雷达技术具有一定研究价值,也为仪器的进一步完善提供了思路。

Abstract:

Migration is one of the. most significant methods in ground-penetrating radar data processing. In this paper the Fourier finite-difference technique is used for migration of phased-array ground-penetrating radar real PGPR data in 2D media. It shows excellent results to reveal the efficiency of the method, also prove the superior science research value of PGPR and give direction for consummating the apparatus next step.
